WATER HEATER.

Application filed March 31, 1927. Serial No. 179,871.

This invention relates to a novel water heater of that class which isincorporated in a drum located in the smoke pipe of a furnace or stoveand through which the smoke and hot air pass to the chimney, and duringtheir passage through said the water or other liquid which is containedin and passes through said heater.

The object of the present invention is to provide a heater of this classthat shall be simple of construction, contain few parts, easilyinstalled, and so constructed that the water unit or container may beremoved from the drum for the purpose of cleaning or renewing the arts.

Another 0 ject being to provide in a heater of the drum type, a watercontainer that shall provide a large heating surface to the action ofthe smoke and heat, and also be provided with means for regulating theheat.

-With these and other objects in view, my invention consists in'certa-incombination and construction of parts as will be fully described andclaimed in the annexed specification and illustrated in the accompanyingdrawings which forma part thereof and in which like figures of referencerefer to corresponding parts in all of the views, but it is fully unmaybe made without departing from the spirit of the invention.

In the drawings: i

Figure 1 shows a cross sectional view of the heater without the damper,but showing the style of header used.

Figure 2 is a top plan view of the heater. Figure 3 is a front elevationof the heater.

Figure 4 is a vertical sectional view of the heater, showing theconstruction of the same.

smoke and heat has a. free passage therethrough.

The drum 11 is constructed of suitable material in the form of acylinder, closed on the ends by a top 12 and a bottom of the drunill andwhich are secured drum they heat the means for removing the water 13,both pro-' vided with the flanges 14 which embrace the' ends thereto inany suitable manner such as welding or by rivets, and each of these ends12 and 13 are provided with a flange or collar to hold the smoke pipe10, and at a suitable point near the top of said drum 11 is provided anopening which is closed by a damper 15 mounted in'a frame 16 secured tosaid drum l1.

lVithin said drum 11 is placed the water container or unit, whichcomprises two headers 17, which are secured together by a series ofpipes 18 to form a water heater, which will have a large heatingsurface, as a number of small pipes will not only present a greatersurface to the hea-t,.but by'confining the water in asmall space it willheat much quicker than it would in a large single pipe or spiral coil.

Each of these headers 17 is formed with a side outlet 19 and an endoutlet 20, to either of which the water pipes 21 and 22 may besecured,-the other outlets being closed by the caps 23.

For mounting the water unit. in the drum 11, the drum 11 is formed onits rear with a cutout portion extending from top to bottom, and theadjacent edges are folded as shown in Figure 6, to form a groove 24,within which is slidably mounted a slide 25, which is formed with twoholes near its ends, through which the inlet and outlet water pipes 21and 22 may pass. i

The top and bottom of said drum are also formed with openings extendingfrom the edge inward towards the center and which are also provided withsimilar grooves and with the slides 26 and 27, which are formed with acutout rear portion designed to embrace the water pipes or the nipples28 as the case may be, and close the drum, rendering the same smoketight.

For securing the unit in the slides 25 and 26 and 27, the slide 25 isfirst placed over the pipes 21 and 22, and the collars 29 are secured onsaid pipes in contact with the surface of said slide 25; and this unitis slid into the grooves 2 1; the top and bottom slides 28 and 27 arethen put in place and secured by the'caps 23.

This arrangement allows of the removal of the water unit for the purposeof cleaning or renewal ofparts. Also the drum 11 may be provided withside inlets 30 for the smoke pipe 10, such being closed by caps 31 whennot used.

For regulating the amount of heat applied to thewater container, thedrum 11 is provided near the u per end with a damper 15 which is mountein a frame 16 secured to the drum and said damper is pivoted therein andactuated by a handle 34.

Said damper 15 swings inwardly, and is provided with the flanges orwings 35, on the ottom, top and near the end opposite the hinge thereofwhich tend to deflect the cold air and prevent its direct action on thewater container, thus mixing cold air with the smoke and heat withoutproducing a chill on the water pipes. Having thus described myinvention, what I claim as new and desire to secure by Letters Patent,is:

'25 In a liquid heater of the clas described, comprising a drum formedwith smoke pipe connections, and an opening in the'side there of, acover for said opening, a liquid container mounted within said drum',-water connections extending through said cover and secured therein, ofa damper mounted in said drum opposite said liquid container, and

means comprising a flange attached to said damper for preventing adirect draft upon the liquid container.

3. In a liquid heater of the class described,

comprising a. heating drum formed with openings in its side, top andbottom, covers adapted to be seci red adjacent said openings forcovering the same, a liquid container mounted within said drum," inletsand outlets secured to' said container and extending through said coversand secured thereto, a deflecting dampersecured to said drum and meansattached to said damper for preventing a direct draft upon saidcontainer.

- In testimony whereof I hereunto aflix my signature.
